8 Claims. 1

This invention relates to new and useful improvements in mechanical coin wrappers and the primary object of the present invention is to provide a device for the reception of a selected amount of similar coins and including novel and ff improved means for quickly and readily placing a wrapper about the coins to retain the same in a small, compact package.

Another important object of the present invention is to provide a mechanical coin wrapper including novel and improved means for conveniently tightening a wrapper about a stack of .similar coins that are inserted in the device.

A further object of the Apresent invention is to provide a coin wrapper including novel and improved means for guiding a Wrapper to be spirally wound about a stack of coins.

A still further aim of the present invention is to provide a coin wrapper that is simple and practical in construction, strong and reliable in use, neat and attractive in appearance, relatively inexpensive to manufacture, and otherwise well adapted for the purposes for which the same is intended.

Other objects and advantages reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming part hereof, wherein like numerals referto like parts throughout, and in which:

Figure 1 is a perspective view of the present invention showing the wrapper partially rolled Within the tubular body;

Figure 2 is a side elevational view of Figure 1, and with parts thereof broken. away and showing sections;

Figure 3 is an enlarged transverse vertical sectional view taken substantially on the plane of the section lines. 3-3 of Figure 1;

Figure 4 is an enlarged longitudinal vertical sectional view of the actuating mechanism and guide supporting the same, and with dotted lines showing the position of the actuating mechanism when it is desirable to remove the package of coins from the device; and,

Figure 5 is a plan View of the wrapper used in conjunction with the present invention.

Referring now to the drawings in detail, wherein for the purpose of illustration, there is disclosed a preferred embodiment of the present invention, the numeral I0 represents a tubular body having a longitudinal slot I2 in one side. Slidably and rotatably mounted in one end of the body, is an actuating rod I4 having a substantially frusto conical nger gripping portion (o1. sas- 2) I6 at one terminal. Removably secured on the opposite terminal of the rod I4, is a retaining plug I8 having a central recessed portion 20 that receives a nut 22 threadingly engaged on rod I4.

Also removably secured on rod I4, is a beveled plug 24, preferably of a resilient material, having its reduced face bearing against one face of plug I8.

An angle iron guide and supporting member 26 having its longer preferably concavo-convexed leg 28 rigidly secured by suitable means to the outerperiphery of the body I0, is provided with an aperture `3i) in its shorter leg 32 that slidably and rotatably engages rod I4. A coil spring 33 loosely mounted on rod I4 is biased between the annular hub portion 34 of plug 24 and the inner face ofleg 32, to normally retain plug I8 and 24 within the body I0 at one end. Preferably, a substantially frusto conical washer 36 carried by the outer face of leg 32 about aperture 30, limits the movement of rod I4 relative to the guide 26 in one direction. f

A longitudinal guide bar 38 which is spaced parallel to one edge of slot I2, has its ends turned outwardly and these legs are rigidly secured to the body I0 by any suitable means. The opposite edge 40 of the slot is turned outwardly for a purpose which will later bek more fully described.

In practical use of the device, a plurality of similar coins are placed into the open end of the body I0 to form a stack supported by the retaining plug I8.l The shorter edge of a substantially trapezoidal wrapper 42 is inserted between guides 38 and one edge of the slot I2 to pass about the inner periphery of the tubular body and to be spirally wound about the stack of coins within the body. It should be here noted, that the diameter of the retaining plug I8 is slightly smaller than the diameter of the coins, that the diameter of the plug 24, at its larger portion, is greater than the diameter of the coins, and that the diameter of the body I0 is slightly greater than the diameter of the coins plus the wrapper wound thereabout. Further, the shorter parallel edge of the wrapper is also wound about the plug 24 during its winding about the coins. By pressing inwardly upon the end of the body adjacent plug 24, the wrapper will be pressed tightly against the plug 24 so that when the knob I6 is turned in a counter clockwise direction, the plug 24, which is slightly larger than the diameter of the coins, will frictionally bear against the inner periphery of the wound wrapconjunction with the accompanying drawings it`= is believed that a clear understanding-i of-.fitheconstruction, operation and advantages of the device will be quite apparent to those skilled-iris this art. A more detailed description is,.aceor.d-.-..
